ATLANTA (WXIA) -- One year ago, Emory University Police alerted students that a rape had been reported at a fraternity house.

Fraternity and sorority social activities were suspended for a month while police, the university and the Sigma Alpha Epsilon National Chapter launched separate investigations.

So far, the outcomes of those investigations have not been made public.

The police investigation has been completed, but Emory University Police and the University say there are still more steps in the legal process – a year after that reported rape, though one legal expert said rape investigations usually take a few months.

It was the SAE house that a female student reported she was raped at about 10:30 p.m. on Halloween 2014.

NEWTON COUNTY, Ga. -- A female student at Emory's Oxford College is facing charges over a threat posted to social media. According to arresting officers, Emily Hikari Sakamoto said it was all a joke. Now some students are asking why it took administrators so long to let them know about the threat.

Classes will resume at Oxford College Wednesday morning, after a fall break holiday. But many students say, it's not just the threat that's got them upset, it's what, they say, they did not get from administration.

ATLANTA -- Police say that an Emory student, arrested for threatening to carry out a mass shooting at Emory's Oxford College, told the arresting officer she meant it as a joke.

Other Emory University students told 11Alive's Blayne Alexander the threat was posted to Yik Yak, an anonymous messaging service. Students screen-captured the threat - later attributed to Emily Hikari Sakamoto - and called 911. The message said, "I'm shooting up the school. Tomorrow. Stay in your rooms. The ones on the quad are the ones who will go first."

The threat was specific to Emory's Oxford College in Newton County, where she is a sophomore, authorities said.

ATLANTA -- Watching brilliant doctors chest bumping with the enthusiasm of college coeds is always a good time. The story behind the picture is a reboot of last summer's 'The Ice Bucket Challenge,' a challenge the heads of Emory's ALS Center are issuing again.

Emory has one of the largest centers for ALS in the country, so their lead team stood in front of Emory's School of Medicine to promote the 'Every August until a cure campaign,' encouraging people to do it again, to donate money again, to help research and find a cure for ALS.

Doctors Nicholas Boulis and Jonathan Glass bumped chests after getting the buckets dumped on their heads. They said they will do this every August, until there is a cure.

ATLANTA -- An Emory University professor was arraigned, Wednesday, on child pornography charges in U.S. District Court.

Kevin M. Sullivan, 60, of Atlanta who is still listed on the university’s website as a professor in the epidemiology department, was arraigned on federal charges of receiving and possessing child pornography.

“Sullivan is charged with downloading images that record the sexual abuse of children,” said U.S. Attorney John Horn. “We remain committed to the primary goal of Project Safe Childhood, which is to protect children by finding and prosecuting those who exploit children through child pornography.”

ATLANTA -- The search for two suspects sparked a campus-wide alert at Emory University Tuesday morning.

DeKalb County Police Captain Steven Fore told 11Alive News it started when officers responded to a robbery and carjacking on North Indian Creek Dr. Two men said they were getting into their Jeep Wrangler when they were approached by two young black men. They were dressed all in black and carrying handguns. After forcing the two victims out of the Jeep, the suspects fled in the Jeep.

ATLANTA-- Emory University has apologized for mistakenly issuing a tornado warning during Tuesday night's storms. The university initially said it did so out of what it called an abundance of caution – even though there were no tornado warnings issued by the National Weather Service.

Emory issued the warning on Twitter, on its text and email alerts, and folks at Emory say the university even sounded warning sirens – all for a tornado warning that wasn't.
